Abstract
A cable having low values for resistance, inductance, and capacitance. The cable includes a plurality of conductors for each signal or leg, which may be configured as a braid of three subsets of braids of bonded pairs of insulated conductors. The bonded pairs may be twisted or untwisted, in close proximity such that inductance is reduced via magnetic field cancellation. Each leg may be separate and parallel, rather than interwoven or braided together, increasing the distance between the two signals and reducing capacitance. The legs may be positioned close to each other, such that their magnetic fields cancel to further reduce inductance.
Claims18
A cable providing low capacitance, low inductance and carrying multiple polarities of a signal, comprising:
- a first leg comprising a first plurality of braided insulated conductors for carrying a first polarity signal;
- a second leg comprising a second plurality of braided insulated conductors for carrying a second polarity signal;
- and
- a securing material holding the first leg adjacent to and separate from the second leg;
- wherein the first leg and second leg each comprise:
- a braid of three sets of conductors, wherein each of the three sets of conductors further comprises:
- a braid of three pairs of insulated conductors.
A method for constructing a cable providing low capacitance, low inductance and carrying multiple polarities of a signal, comprising:
- braiding three pairs of insulated conductors to create a subset of braided conductors;
- braiding three subsets of conductors to create a first leg;
- and
- securing two legs separate from and adjacent to each other with a securing material;
- wherein braiding three pairs of insulated conductors and braiding three subsets of conductors is performed simultaneously.
